I'm trying to write a script to add the mograph camera shader to the luminance channel of a material, and then set the Camera target. I can insert other shaders, but I cannot locate in the documentation the correct way to instantiate that shader, nor how to modify the property of a shader once added to the material.
Solved Mograph Camera Shader from Python
here's an example on how to create a camera shader and set the link of the camera.
Be aware you need to create the shader using it's ID so it could be changed in the future.
I've used a script from @m_adam as a base and just added the camera shader stuff. You can thanks him a lot ^^
